Answer:

C \frac{y^\frac{1}{2} }{xz^2}

Step-by-step explanation:

To find an equivalent (or equal) expression, simplify the operations using exponent rules. Apply the power to a power rule and the negative exponent rule to turn all negative exponents positive. This is applied by moving any bases with negative exponents to the denominator.

(x^\frac{1}{2}y^\frac{-1}{4}z)^{-2} = (x^\frac{-2}{2}y^\frac{2}{4}z^{-2})=\frac{y^\frac{1}{2} }{xz^2}

F(x)=6x-18 sub in f(x/3), f(x)/3
arlik [135]

These are two separate problems: in the first we will have to substitute in a new value for x into the original equation and in the second we will manipulate the preexisting equation for f(x).

To begin, we will sub in f(x/3). To do this, we will substitute each variable x in the equation (in this case there is only one) with x/3, and then simplify the resulting equation.

f(x) = 6x - 18

f(x/3) = 6(x/3) - 18

To simplify, we should distribute the 6 on the right side of the equation.

f(x/3) = 6x/3 - 18

Now, we can divide the first term on the right side to finalize our simplification.

f(x/3) = 2x -18

Secondly, we are asked to find f(x)/3. To do this, we will take our original value for f(x), and then simplify divide that entire function by 3.

f(x) = 6x - 18

f(x)/3 = (6x-18)/3

This means that we must divide each term of the binomial by 3, so we are really computing

f(x)/3 = 6x/3 - 18/3

We can simplify by dividing both of the terms.

f(x)/3 = 2x - 6

Therefore, your answer is that f(x/3) = 2x - 18, but f(x)/3 = 2x - 6. It is important to recognize that these are two similar, yet different, answers.

Hope this helps!

Brooke had 70 chairs but he had less than20 rows how many chair he can put on each row
RideAnS [48]
Put in a equality

20 > (70/x)

then you solve 

20x > 70

x>70/20

x> 3.5    you can not put part of a chair in a row so you round up

****You can put  4 or more chairs in a row****

Need help finding this answer
Cloud [144]

Answer: The first option.


Step-by-step explanation:

1. The formula for calculate the perimeter is:

P=2l+2w

Where l is the lenght and w is the width.

2. The first perimeter is:

P_1=2(105m)+2(12.5m)=235m

3. If you multiply the dimension by a scale of factor of 2, is the same as write the following expression:

P_2=2(2l+2w)

Where 2l+2w is the first perimeter.

4. Then:

 P_2=2(235m)=470m
